Tell us what you really think, Kim!

In a pair of previews for the upcoming episode of Keeping Up With the Kardashians, Kim absolutely lets loose on Tristan Thompson, and it’s a sight to behold!

Things start off mildly enough with Kim expressing her frustrations to Scott Disick.

It’s a little ironic, but hey — who knows more about mistreating Kim’s sisters than Scott?

“So I feel like Khloe is living a full double life,” Kim explains to Disick.

“She’s in town and I just haven’t seen her. I just feel like Tristan’s here and she’s so nervous for she and I to see each other.”

Yes, like the rest of us, Kim is slowly coming to terms with the fact that Khloe is not going to dump Tristan.

Scott then launches into a nonsensical, word salad defense of douchebag behavior that could earn him a spot as the next White House press secretary:

“Everybody wants to be protective of their family,” Disick says.

“But I think sometimes when people get too caught up when it’s like a negative protection and not always being there with the positive, then everybody feels kind of like attacked.”

From there Kim launches a more direct attack after learning that Tristan has blocked her on social media.

Note how the Calabasan female expresses anger without ever altering her facial expression or abandoning her deep vocal fry:

“He blocked me, what a f–king loser. Literally, what a fucking loser,” Kim says.

“He blocked me on Instagram … like, how old are you?” she continues.

“He’s 27, only 27-year-olds know how to block,” Khloe remarks.

“I don’t even know how to block someone.”

Of course, these scenes were shot several months ago and much has changed since then.

These days, Kim has forgiven Tristan and the NBA star has been welcomed back into the Kardashian fold.

But clearly, the most shocking thing in all this is that there was a time — just a few months ago — when the Kardashian sisters had no idea how to block someone on Instagram.

And sadly, that might still be the case.
